The device tree information and dmesg information are as above. It seems that the SDIO is not functioning. I captured the signals with a logic analyzer and found that there is no clock signal. Therefore, I suspect that it is still an issue with my configuration. I'd like to inquire if there are any similar cases. Thank you!
Use cases
We are currently in the planning phase of designing an electroencephalogram (EEG) acquisition device that uses Wi-Fi to transmit EEG signals.
